The yellow sac spider is showing up in 2008-2009 Honda Accords. This is just 6 days after Mazda recalled over 52,000 of its vehicles because of the 8 legged creature.

Now Honda is reporting that the yellow sac spider is also appearing in the Honda Accord. The spiders create the same problem by spinning their webs in the vent hose of the evaporative canister . When the vapors build up, the emission system is triggered to vent the canister. This causes the computer to illuminate the Malfunction Indicator Light (MIL). In the Mazda cars, the blockage by the spider webs creates an abnormal excess vacuum in the fuel tank. Repeated exposure to the vacuum causes stress on the fuel tank and could cause it to crack, leak fuel and present a fire hazard. This does not occur in the Honda.

Honda spokesperson, Chris Martin theorizes that the spider may be getting in between the gaps in the fuel cover door. The gaps are present so that moisture and dirt do not get trapped behind the door. From there, the spider can proceed down the evaporative canister vent tube to spin its web.

There is no official count of how many times Honda has seen this problem, but it has been seen mostly in the 2008, 2009 year Honda Accord.

Honda has not recalled any Honda Accords, but they released a technical service bulletin to all dealers so that they are aware of the problem. (TSB 08-087). The repair consists of cleaning the vent host or drain box and installing a spring in the drain box.

– The yellow sac spider is causing problems for the 2009-2010 Mazda 6 automobiles. These spiders have been found spinning webs in the evaporative canister vent line of the 4 cylinder cars. This could cause the line to be blocked and cause vapors to build up in the canister.

The Mazda emission-control system will remove the vapors accumulated in the canister, but if the vent line is clogged by the yellow sac spider web, the process creates an excessive negative pressure in the fuel tank.

The repeated exposure to negative pressures could cause the tank to fail, fuel to spill and create a fire hazard.

It is unknown how the spiders are getting into the vent line.

Mazda is recalling over 52,000 of its vehicles because of the spider threat. There have been 20 incidents of the yellow sac spider, but none have resulted in fires.

Notification of the recall will be sent out to owners in a few weeks. The repair will consist of cleaning and replacing hoses and replace the fuel tank if it is compromised.
